Abstract The iodometric method is a routine analysis method to determine glucose content and usually used in comprehensive quantitative analytical chemistry experiments. The miniaturization of the traditional iodometric method for determination of glucose content is studied,some influential factors such as amounts of sodium hydroxide, titration speed, reaction temperature, storage time, amounts of acid, shaking extent as well as the moment of addition of starch solution were researched. The experimental results showed that the miniaturized titration method may achieve the same precision and accuracy of the conventional titrimetric analysis, and satisfy the requirements of titrimetric analysis experimental teaching. At the same time, this method can greatly reduce the experimental reagent wastage, save experimental expenditure more than 80%, enable students to establish the concept of green chemistry and environmental protection awareness, and raise the quality and benefit of the talent training.
